Patented Dec. 13, 1938 UNITED STATES WHEEL Henry Lasenby Rose, Victoria, British Columbia, Canada Application November 2, 1936, Serial No. 108,794 In Canada November 22, 1935 3 Claims.

My invention relates to improvements in quick detachable wheel hubs. The objects of the invention are to provide means for securing the component parts of the hub together which will hold them securely in fixed position against all strains incidental to driving and to enable them to be separated by simple manipulation of very few parts. A further object is to provide means whereby the wheel is supported on the hub prior to fastening, so that the registration of the hub parts may be obtained without having to support the Weight `of the wheel by muscular effort.

AThe invention consists essentially of a hub and a shell slidably mounted thereon and a concentrically disposed fastening means for securing said shell against endwise movement upon the hub, as will be more fully described in the following specification and shown in the accompanying drawing, in whichzl Fig. l is a longitudinal sectional view of the invention.

Fig. 2 is a transverse view showing the hub thread.

Fig. 3 is a transverse view showing the cap nut thread.

Fig. 4 is a projection of the thread showing the lead for the cap nut threads.

Fig. 5 is a fractionated longitudinal sectional view of a modification.

Fig. 6 is a longitudinal sectional view showing a modified locking means.

Fig. 7 is a fractionated plan view of same.

In the drawing like characters of reference indicate corresponding parts in each figure.

The numeral I indicates an axle to which is secured a hub 2.` The hub 2 consists of a sleeve 3 provided at its inner end with a ange 4 which is provided with a plurality of studs 5 arranged equidistantly around the sleeve. The studs 5 are bevelled off at their free ends as at E and are provided with a sloping shoulder 'I at their connecting ends. The sleeve 3 is provided at its inner end with a tapered shoulder 8 and is provided at its outer end with a breech block thread 9 or a thread which is cut away at regular intervals of its circumference to define gaps I0.

Fitted upon the hub 2 is a Wheel shell II which consists of a cylindrical portion I2 to which spokes I3 are secured in any desired manner. A ange III extends inwardly from the portion I2, and the inner periphery of the ange is connected with a sleeve I5 which ts snugly yet freely upon the sleeve 3 of the hub 2. The outer end of the sleeve I5 is outwardly splayed as at IB, and the intersection of said sleeve with the shell ange It is splayed to 'it the tapered shoulders of the hub 2. The flange I4 is provided with apertures II through which the studs 5 pass, but the margins of said apertures come to rest adjacent the base of the sloping shoulder I of the said studs so as to provide a positive and accurate ultimate `engagement of the flange I4 while allowing the apertures I'I to be easily brought into register with said studs.

The breech block thread 9 is engaged by a cap nut I8 havin-g a corresponding thread I9 divided by corresponding gaps 20, so .that in fitting the cap nut the threads of the nut are passed vlongitudinally along the sleeve through the gaps I0 until it is bottomed, and then turned to right or left according to the thread being right or left hand as the case may be. In order that the meeting ends of the segments of the threads 9 and I9 do not abut to prevent free turning movement, as would be the case were the ends cut oft' at substantially a right angle to the line of the threads, the entering ends of the male or sleeve threads 9 are sloped off as at 2I so that on initial turning movement being given to the cap nut its threads ride up the sloped ends of the corresponding threads and allow the threads to engage with ease.

The inner peripheral edge of the cap nut I8 is tapered as at 22 to conform to the splay I6 of the sleeve I5, so that when the cap nut is screwed up securely the ends of the sleeve are concentrically aligned between the tapered shoulder 8 of the hub 2 and the taper 22 of the cap nut I8. The cap nut I8 is provided at its free end with a stud 23 which is engaged by a nut 24 preferably rotatably mounted in a cover plate 25. The cover plate 25 is provided with a bevelled flange 20 which abuts a corresponding ange 2l upon the free end of the cylindrical portion I2 of the wheel shell II. This cover plate is provided with inwardly projecting lugs 23 which are adapted to engage 'lats29 of the cap nut I8 in a similar manner to the jaws of a wrench.

In the modificati-on shown in Figure 5 insteadof providing a plurality of convolutions of thread on the hub sleeve and cap nut. two segments of convolutions -only are provided on each of the parts, the male thread being at the outer end of the sleeve as at 30 and the female thread of the nut cap being at the inner end as indicated in dotted line as at 3l.

In the modified locking means shown in Figures 6 and 7, the cap nut I3 is provided with arcuate slots 32 which register with the gaps 20, through which slots, legs 33 of a U-shaped member 34 project to ll said gaps and the gap ID of the hub sleeve. When the cap nut is screwed into place the U-shaped member is inserted and is held in position by a nut 35 upon thestud 23 which passes through said U-shaped member. It may be preferred to taper one or both sides of the legs 33 as at 36 in order to assist in driving the threads of the hub sleeve and cap into tighter engagement.

When tting a wheel, the shell Il is slipped onto the sleeve 3 of the hub 2 and is rocked thereabouts until the studs 5 register with the apertures I1 when it is thrust substantially into contact with the flange 4. The cap nut i8 is then applied to the thread 9 and tightened up with a suitable wrench, nally the cover plate is then placed in position and the nut 24 screwed up upon the stud 23. When this is done, the frictional contact between the coacting surfaces of the cover plate flange 26 and the outer flange 21 of the shell Il and the grip of the nut 24 0n the stud 23 is suiicient to definitely lock the cap nut against removal through road shock, starting torque or any other strain that the wheel might be subjected to.

In the modied form shown in Figures 6 and 7, the legs 33 of the U-shaped member 34 are projected into the gaps ID and 20 and are held in adjusted position by the nut, thus locking the nut cap against removal.

What I claim as my invention is:

1. A quick detachable wheel comprising a. hub

sleeve having at its outer end a breech block.`

thread, a wheel shell having a sleeve adapted t0 slidably engage the hub sleeve, means for preventing rotation of the shell sleeve upon the hub sleeve, a cap nut adapted to engage the breech block thread and bind against said shell sleeve, and means threadedly engaging the cap nut for frictionally engaging the periphery of the shell and for locking the cap nut against rotation.

2. A quick detachable wheel comprising a hub sleeve having at its outer end a breech block thread, a wheel shell having a sleeve adapted to Y slidably engage the hub sleeve, means for preventing rotation of the shell sleeve upon the hub sleeve, a cap nut adapted to engage the breech block thread and bind against said shell sleeve,

and means for locking the cap nut to the hub sleeve, said locking means consisting of a bevelled flanged member extending across the shell and contacting therewith, and screw means concentric with the member for joining said member to the cap nut.

3. A quick detachable wheel comprising a hub sleeve having at its outer end a breech block thread, a wheel shell having a sleeve adapted to slidably engage the hub sleeve, means for preventing rotation of the shell sleeve upon the hub sleeve, a cap nut adapted to engage the breech block thread and bind against said shell sleeve, and means for locking the cap nut to the hub sleeve, said locking means consisting of a plate having a bevelled peripheral flange adapted to bear upon a complementary peripheral surface of the shell, and a concentrically mounted screw for fastening the plate to the cap nut.
